Remember I made the concept of absolutely infinite maze just by wrapping player to opposite side and making it absolutely invisible? For those who don't know here's the link
One time I've got quite similar idea for the actual game. Just a little option to make level be infinite by connecting level border's edges and corners side by side. That means if you put the boulder and space under it will be cycling through around without stopping. The border steel walls will also be just ignorable.
Could that be possible on real game's engine?
If yes, so if this will be in game how could it look in the editor while editing? Like border walls are replaced with the elements which are rendering from the other side? I'm just curious.
